SEC. 504. PERMIT REQUIREMENTS AND CONDITIONS.
  (a) Conditions.-   Each permit  issued under  this title  shall
include  enforceable   emission  limitations  and   standards,  a
schedule of  compliance, a requirement that  the permittee submit
to the permitting authority,  no less often than every  6 months,
the results of any required monitoring, and such other conditions
as   are   necessary  to   assure   compliance  with   applicable
requirements  of  this Act,  including  the  requirements of  the
applicable implementation plan.
  (b) Monitoring  and Analysis.-   The Administrator may  by rule
prescribe procedures  and methods for determining  compliance and
for monitoring  and analysis  of pollutants regulated  under this
Act,  but continuous emissions monitoring need not be required if
alternative  methods  are  available  that  provide  sufficiently
reliable  and  timely  information  for  determining  compliance.
Nothing in  this  subsection shall  be  construed to  affect  any
continuous emissions monitoring requirement of title IV, or where
required elsewhere in this Act.
  (c)  Inspection, Entry, Monitoring,  Certification, and Report-
ing.-   Each  permit  issued under  this  title shall  set  forth
inspection,  entry,  monitoring,  compliance  certification,  and
reporting requirements to assure compliance with the permit terms
and conditions.  Such monitoring and reporting requirements shall
conform to  any applicable  regulation under subsection  (b). Any
report required to be  submitted by a permit issued to a corpora-
tion  under this title shall be signed by a responsible corporate
official, who shall certify its accuracy.
  (d)  General Permits.-    The permitting  authority may,  after
notice and opportunity for public hearing, issue a general permit
covering  numerous similar  sources.  Any  general  permit  shall
comply  with all  requirements applicable  to permits  under this
title. No source  covered by  a general permit  shall thereby  be
relieved from the obligation to file an application under section
503.
  (e) Temporary  Sources.-  The permitting authority  may issue a
single permit authorizing  emissions from  similar operations  at
multiple  temporary locations.  No  such permit  shall be  issued
unless it  includes conditions  that will assure  compliance with
all the  requirements of this  Act at  all authorized  locations,
including, but  not limited to, ambient  standards and compliance
with any  applicable increment  or visibility  requirements under
part C of title I. Any such permit shall in addition require the 
owner or  operator to notify the permitting  authority in advance
of each  change in location. The permitting authority may require
a separate permit fee for operations at each location.
  (f)  Permit Shield.-  Compliance with a permit issued in accor-
dance with  this title shall  be deemed  compliance with  section
502. Except  as otherwiseprovided  by the Administrator  by rule,
the permit may also provide that compliance with the permit shall
be deemed compliance with other applicable provisions of this Act
that relate to the permittee if- 
       (1)  the permit  includes the  applicable requirements  of
     such provisions, or
       (2)  the  permitting authority  in  acting  on the  permit
     application makes  a determination relating to the permittee
     that such  other provisions (which  shall be referred  to in
     such  determination)  are  not  applicable  and  the  permit
     includes the determination or a concise summary thereof.
Nothing  in the  preceding  sentence shall  alter  or affect  the
provisions  of  section  303,  including  the  authority  of  the
Administrator under that section.
